Dark photons are among the simplest extensions of the Standard Model (SM): a renormalizable kinetic mixing with the ordinary photons generates a coupling between the dark photon and the SM electromagnetic current. Such coupling can be used to probe the parameter space of the model, resulting in severe bounds. In this talk, I will discuss a modification of such a scenario in which additional dark photon couplings are present. The discussion will be framed in the context of a “dark EFT” constructed out of the dark photon and SM fields. Focussing on the effect of dark lepton dipole moments, I will show how current bounds may be drastically modified even for relatively heavy new physics.
